What causes a p0758 trouble code on a Chevy Silverado?

What Causes A P0758 Trouble Code? In the majority of cases, a bad 2-3 shift solenoid is the cause of the P0758 trouble code lighting up the check engine light on your Chevrolet Silverado (GMC Sierra). Other things that can cause a P0758 trouble code are: Damaged or loose solenoid connector.

What does DTC p0758 mean in Powertrain Control Module?

When the Powertrain Control Module (PCM) detects a continuous open, short to ground or short to power in the 2-3 Shift Solenoid (SS) valve circuit, then DTC P0758 sets. The 2-3 Shift Solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves.

What causes check engine light and trouble code p1860?

GM has issued a technical service bulletin 01-07-30-002C for the vehicles listed below. GM has advised that the most likely cause for a check engine light and trouble codes P0740, P0753, P0758, P0785, and P1860 may be a faulty ignition switch that causes an open circuit to the transmission.

Where is the trouble code on a GMC?

When retrieving GMC trouble codes with an OBD II scan tool, proceed as follows: 1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover. 2. Turn the ignition on.

What does the OBD code p2761 mean?

P2761 is a specific OBD-II code that indicates a problem with the main circuit of the pressure control solenoid within the TCC being in an open position. The TCC connects the turbine shaft to the torque converter’s shell, creating a one-to-one connection between engine output and transmission input.

What does the p2761 code on a torque converter mean?

What the P2761 code means. P2761 is a specific OBD-II code that indicates a problem with the main circuit of the pressure control solenoid within the TCC being in an open position. The TCC connects the turbine shaft to the torque converter’s shell, creating a one-to-one connection between engine output and transmission input.

What was the p0783 code on a 2001 Chevy Silverado?

We’re working on a 2001 Chevy Silverado 2500HD.It was stuck in limp mode. We first got the P0783-85 codes, so we replaced both shift solenoids, as well as the wiring harness. Still shot the same codes and was stuck in limp mode. So we replaced the transmission. Still didn’t work.

When to replace a shift solenoid p0753 trouble code?

A common mistake made by mechanics when diagnosing a P0753 trouble code is to replace a shift solenoid because they believe it has caused the problem, when in actuality the problem lies somewhere else. How serious is the P0753 code?

What causes a p0753 trouble code on a PCM?

A common cause of the storage of a P0753 trouble code in the PCM is a faulty shift solenoid. Some other causes include blockage in the hydraulic system inside of the transmission, a mechanical failure in the transmission, a low transmission fluid level, and dirty or contaminated transmission fluid.

What are the trouble codes for the B solenoid?

The trouble codes related to this, the “B” solenoid, are codes P0755, P0756, P0757, P0758 and P0759 based on the specific malfunction that alerts the PCM to set the code and illuminate the Check Engine Light. These codes will also be associated to the A, B or C solenoid circuit.

What are the DTC codes for Shift Solenoid?

These codes will also be associated to the A, B or C solenoid circuit. If you have an Overdrive or other transmission warning lamp, it may be illuminated also.

What causes p0785 shift timing solenoid malfunction?

Causes for this P0785 transmission code may include: Damaged or defective shift timing solenoid Pin/connector problem (corrosion, melting, broken lock tab etc.) What are some P0785 troubleshooting steps?

These codes will also be associated to the A, B or C solenoid circuit. If you have an Overdrive or other transmission warning lamp, it may be illuminated also.

What does p0758 mean in a powertrain computer?

When the code P0758 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is not seeing the specified rpm change that occurs during a shift from 2nd gear to 3rd gear.
